specific Embodiment 1
[0034] Specific embodiment one: as figure 1As shown, a lightning arrester device for overhead lines includes a bracket 1 and a lightning arrester assembly 5 . A cross-arm slot 2 is arranged on the bracket, and a bolt through hole is arranged on the side wall of the cross-arm slot, and a fastening bolt 3 is arranged on the bolt through hole.
[0035] The lightning protection assembly 5 includes a lightning arrester 5.1 fixed on a bracket, a lower conductive head 5.2 arranged on the upper end of the lightning arrester, an upper conductive head 5.3 located above the lower conductive head, and a conductive lead 5.4 electrically connected to the upper conductive head. A discharge gap is formed between the lower conductive head and the upper conductive head. In this embodiment, the lower end of the arrester is fastened and fixed on the support by bolts, and the arrester is a zinc oxide arrester. Of course, the arrester can also be other arresters.
[0036] The lightning arrester d...

The invention discloses a lightning arrester device for an overhead line, and aims to provide a lightning arrester device which can perform live-line installation by using an insulating rod operationmethod under the condition of not influencing normal operation of the overhead line so as to effectively solve the problem that a live-line work vehicle needs to pass through an area where the overhead line is inconvenient, the lightning arrester can be installed only after the overhead line is powered off, and the normal operation of the overhead line is influenced. The device comprises a support, a cross arm clamping groove is formed in the support, a bolt through hole is formed in the side wall of the cross arm clamping groove, and a fastening bolt is arranged on the bolt through hole; thelightning protection assembly comprises a lightning arrester fixed on the support, a lower conductive head arranged at the upper end of the lightning arrester, an upper conductive head located above the lower conductive head and a conductive lead electrically connected with the upper conductive head, and a discharge gap is formed between the lower conductive head and the upper conductive head.
Description
technical field [0001] The invention relates to a lightning arrester device, in particular to a lightning arrester device for an overhead line. Background technique [0002] After the lightning arrester used on the overhead line is aging or damaged at present, since the lightning arrester in the prior art generally cooperates with the stud and the nut at the lower end of the lightning arrester, the lightning arrester is fixed on the cross arm of the pole. The studs are inserted into the mounting holes on the cross-arm of the pole from top to bottom, and then the nuts are installed on the studs, and the nuts are locked to fix the arrester on the cross-arm of the pole; due to specific installation, It is necessary to insert the studs at the lower end of the arrester into the installation holes on the cross-arm of the electric pole from top to bottom, which makes it impossible for the arrester in the prior art to be installed on the cross-arm of the electric pole by using the i...
